EMC

EMC

Interference is probably the single biggest threat to the continuance of the hobby for those with an urban or suburban location particularly in the HF spectrum.

In 2006 we had a fairly major house extension, which meant I had to go QRT for about a year. When I started to get QRV again I discovered I had lots of EMC issues, mostly interference to me. The majority of it was due to domestic electrical items that had appeared in our house, either associated with the extension or due to the rise in popularity of the switch-mode power supply in the intervening period.

The following pages are further adventures in EMC from the new QTH in Lawshall, Suffolk.

One of the best articles I've seen on explaining the sources of RFI and how to deal effectively with them is at http://audiosystemsgroup.com/RFI-Ham.pdf. You might also find GM3SEK's pages helpful.
